Development and performance testing of an intelligent platform for top-down construction steel pipe columns

Abstract:

The top-down construction technology has broad application prospects in fields such as urban underground space development and deep foundation pit engineering. However, as the main vertical load-bearing components in top-down construction, steel pipe columns are significantly affected by verticality deviations and errors caused by manual positioning, which have a great impact on construction quality. To improve the positioning accuracy and vertical precision of steel pipe columns in top-down construction, this paper designs and develops an intelligent platform for top-down construction steel pipe columns capable of automatic vertical adjustment and positioning based on the top-down construction process and intelligent control technology. It mainly elaborates on the overall structure, working principle and performance parameters of the equipment, and conducts performance tests on it. The test results show that the vertical precision of steel pipe columns placed by the intelligent platform for top-down construction steel pipe columns is controlled within 1/800, and the positioning accuracy is controlled within ±5mm, which effectively enhances the stress stability of steel pipe columns and improves the project quality. This platform has certain practical significance for promoting the development of top-down construction technology in the direction of intelligence.
